It is awesome.
They reshaped the protoss, gateways are fucking awesome as you can make them into Warp Gates, allowing you to teleport any Protoss base ground unit near a pylon or warp prism. Plus build speed is increase.
Downside only one unit per warp gate, plus a CD to it sadly. But its hella nice warping in a bunch of dark templar behind enemy lines and destroying there economy.
